Grade Eight Science Chapter Two. An ocean current is a large mass of moving water in the ocean. A current moves in one, unchanging direction. There are.

Ocean Currents “Rivers in the Ocean”. Currents Current – a large stream of moving water that flows through the ocean. Capable of moving large amounts.

Ocean Currents. Objective Ocean currents are cause by unequal heating and differences in salinity. The currents distribute heat around the planet.

Movement of Ocean Water

Ocean currents – the movement of water within the ocean water Ocean currents – the movement of water within the ocean water. Caused by water temperature, water salinity, water density, wind, and gravitational pull from the moon.

Gyre – A circular motion of water in each of the major ocean basins.

Upwelling – The upward movement of ocean water from deep in the ocean to the surface.

Downwelling – The downward movement of ocean water from the surface.

El Nino – A time when surface waters are warmer causing nutrient-rich cold water to stay close to the bottom of the ocean.
